Tensions were high during the decision-making process that would lead up to the raid on Osama bin Laden's compound in Abbottabad, Pakistan. Success depended on the precision of the Navy SEALs team in order to kill this slaughterer of thousands.

So, with success met and their mission accomplished, the team had to be sure they'd got their mark:

When bin Laden's corpse was laid out, one of the Navy SEALs was asked to stretch out next to it to compare heights. The SEAL was 6 feet tall. The body was several inches taller.

After the information was relayed to Obama, he turned to his advisers and said: "We donated a $60 million helicopter to this operation. Could we not afford to buy a tape measure?"
